It might be a bit unrelated, but what is your take on infinite regression?
To be fully honest, the possibility of an actual infinite, which is central to the Kalam's second premise, is one of my weaker areas. I'm not much into mathematics, and whether or not an actual infinity can exist is an issue in the philosophy of mathematics. Cantor's set theory entails that an actually infinite set can exist, but the so-called "finitists" are keen to argue against that notion, and I haven't worked out the disputes between them. Getting around my mathematical grey areas, I would say there's a plausible argument for an actual infinite from (again) physics. There's the quantum eternality theorem, and QM models like Caroll-Chen, which, if true, entail that an actual infinity is real. I don't see any way that one could argue these models are physically impossible.
However, nobody disagrees that a potential infinite (think of the limit concept in calculus) can exist. For example, the universe is billions of universe old, and as time passes, the age of the universe will approach infinity (perhaps, never reaching it, depending on how the issue gets resolved). If one denies that T=0 corresponds to a real state of time (how can there be a time of zero time?), then the result would be a universe where, going back on its timeline, you would never actually reach a first instant of the universe's beginning. One might then say that, since every instant of the universe is preceded by another instant, there's no instant of the universe that a divine entity could cause.
